L SE PARATOR FOR SLITTING MACHINES Filed May 1928 Patented Mar. 4, a 1930 UNITED STATES ieaneur OFFICE JOSEPH ATWOOD WHITE, OF MELROSE PARK, PENNSYLVANIA, ASSIGNOR TO THE MOORE & WHITE COMPANY, OF PHILADELPHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA SEPARATOR FOR snrrrmamacnmns Application filed May 4, 19 8, Serial No. 275,121.

My invention relates to certain improvements in machines for slitting paper.

' In this type of machine, after the paper has been cut into sections by the slitting mechanism, it is Wound upon a roll. Heretofore it has been difficult to prevent the several rolls from weaving one into another and this is particularly so where the slitting is done close I to'the winding shaft.

v 11' and 12. These disks are The object of my invention is to provide mechanism that can be located close to the winding shaft and which will separate the several sections of paper after the slitting operation, so that they can be Wound upon the roll without the edge of one section weaving in the edge of an adjoining section.

In the accompanying drawings:

Fi ure l is a diagrammatic view showing the location of my improved separator or spreader;

Fig. 2 is a side view showing the detailed construction of the spreader;

Fig. 3 is a plan View of the spreader shown in Fig. 2; and

Fig. 4 is a view illustrating a modification of my invention.

Referring to Fig. 1, 1 is a roll over which the paper passes towards a roll 2. This roll is a driving roll and the paper passes around the roll and is wound upon a spindle 3 adapted to suitable guides (not shown). The roll of paper as it is formed is supported on the rolls 2 and 4 in the present instance. It will be understood that other methods of sup porting and feeding the paper may be resorted to without departing from the essen tial features of my invention.

5 is a bar which extends across the ma chine, and pivotally mounted on this bar are a series of brackets 6 to which are pivoted arms 7.

The pivot 8 is located as shown inFig. 2, and an adjusting screw 9 extends through the arm and rests upon a bracket 1-0. By means of this screw the arm can be raised or lowered to properly align the separator with the paper passing through the machine.

At the outer end of the arm 7 are two disks eccentrically mounted on a spindle 13 and each disk has a beveled edge as shown in Fig. 3. The disks are rotated by the paper as it is fed through the machine, and as one eccentric disk pushes theedge of the one strip of paper out of line, the edge of the adjoining strip remains in position as that particular eccentric is out of position for the time. As the two disks are connected together, they rotate in unison, so that ,first'the edge of one strip of paper is forced down out ofalignment and clear of the edgeof the other strip and then the edge of the other strip is forced down, while the edge of the first-mentioned strip is clear. Thus, there is an alternate pressing down of the edge of the adjoining strips of paper, preventing the weaving or adhering of one coiled strip to another. This alternate movement of the sheet not only prevents the weaving of the rolls of paper, but also prevents wrinkles from forming in the sheet, as con-. siderably more pressure can be exerted upon the paper, the pressure being removed before wrinkles can be formed.

In Fig. 4, I have illustrated a modification, in which two cams 11 and 12 are mounted on a driven shaft 14 and act upon shoes 9 and 10*, secured to a bracket 6*, which is preferably adjustably mounted on a bar 5*. These shoes bear upon the strips of paper as they are fed through the machine, and the cams alternately act upon the shoes so as to force the strips out of alignment with the other.

I claim 1. The combinationin means for separating adjoining strips of paper, while the said paper is moving from one support to another, of two supports for the paper; means for moving the paper; and means located between the supports for alternately forcing the edges of the two adjoining strips out of. alignment one with the other as the paper is moved from one support to the other.

2. The combination in a separator for a paper slitter, said separator consisting of two eccentrics arranged side by side; and an arm adjoining strips out of alignment one with the other.

3. The combination in a separator, of a series of brackets on which bars are mounted; and arms on the bars, each arm carrying two eccentric pressers, one presser being eccentrically mounted in respect to the other, and each presser having a beveled edge and arranged to alternately press the edges of the strips out of alignment one with the other as the paper travels through the machine.

4:. A separator for a paper slitting machine, consisting of a disk having two eccentric surfaces, one arranged out of line with the other so that they will alternately force the edges" of adjoining strips out of alignment one with the other as the paper is fed past the disk.

5. The combination in a separator for paper, in which the edges of two strips of paper are located close together, said separator consisting of two eccentrically mounted disks arranged side-by-side and located one in advance of the other so that they will alternately force the edges of adjoining strips out of alignment one with the other.
